Barring that, I think varying the scale of the sketches and views, as well as line quality and amount of shading or color, will get the effect you are looking for. Mix between orthographic "side/front/top" thumbnails, and perhaps one or two larger 3-qtr or gestural sketches in the corners.

So I feel bad for dropping this thread a bit...! But full time work has made me lazy outside work! However... I have been playing with sketching in VR, and wondered if anybody else had? I'm still very novice, and struggled switching from perspective sketching to volumetric sketching! But hey, here's to exploring different sketch styles!!
